Resources folder generated by a msi file

Hi guys, how are you?

I am using PB.NET 12.5.2, build 5629 to create a WCF project.

I was wondering about this resources folder, generated in the path  \<webservice>\resources.

When I deploy my project checking the option "Generate setup file", the instalation process creates this folder with all exported datawindows from my project.

On the other hand, if I "deploy directly to IIS", no folder is created.

So, why does PB .NET creates this folder? I think my datawindows are not necessary, unless I need to debug my WCF, am I right?

Thanks!
